RF signal vs S-Video vs Composite

[Serville]

S-Video is better than Composite, that is the norm.
But what about RF signal ?
I have a decoder that has RF connector instead of S-Video.
Will this be less better than S-Video ?

Best to worse analog connections

YPbPr component (red green blue)
S-Video Y/C
Composite
--------------
RF (the worse unless it is the direct feed from the dish, antenna or cable to the primary tuner)

If it is the Ch 3 or 4 stuff, it is the worse quality because it is generated in a $2 RF encoder.

Low end RF still has uses for moving video with audio around the house over long (>100 ft) distances. Baseband composite video suffers more losses as cable lengths increase. High impedance consumer audio over long distance is a larger problem unless you first convert to low impedance 600 ohm balanced connections. This gets expensive.
